Preparation:

Prepare barbecue sauce: In a saucepan, heat oil over medium heat and sauté onion until tender and golden brown. Stir in garlic. Mix in Worcestershire sauce, vinegar, molasses and mustard. Cook and stir 5 minutes, then mix in ketchup, liquid smoke, cold water and cornstarch. Reduce heat to low and continue cooking 10 minutes, until thickened. (You will use 1 cup in the sloppy Joes recipe; reserve remainder for another use.).

Prepare meat, while sauce simmers: In a large skillet, cook meat, onions and garlic over medium heat until meat is no longer pink; drain.
